招聘 mid-level 自由职业 Ruby on Rails 开发者 在 United States

I began learning Ruby on Rails in 2018 but truly started to understand it during COVID-19. Learned to switch the code from ERB to haml for templating, server-side rendering with Hotwire/Stimulus. Analyze the code for accessibility issues and remediate as needed. Integrated HTML5 video playback, Stripe payments integration, Sendgrid email relay services, Google Cloud SDK, Heroku deployment, among others.

💭 Do you have an idea that makes sense in theory, but you haven't gotten it beyond that point? An existing team that could use some direction? Perhaps a product that you've gotten to market, but you're finding it harder to add more and more customized features and keep it performing the way it should? 👋 For a little over a decade now, I've been building clean, maintainable, applications for everything from cyber security, high traffic (millions of transactions per day), credit products, custom learning platforms, to custom storefronts. 🤖 I take a pragmatic approach to development, I'll hear you out, ask some pointed questions along the way, give targeted feedback, and rinse and repeat until we've got a clear vision for your product. You'll be able to give feedback on quick builds that are put together in days / weeks rather than months. This process is called prototyping. 🏆 Prototypes are great, but they won't take into account all the nuances needed for a product to start serving customers, so from there we'll have a conversation about what your "must haves" are in order to get a product in front of customers. Anything that you'd like but isn't a "must" will be outside the scope. This step is where we build an MVP (minimum viable product). The goal here is to get your product to market as fast as possible. Paying customers are the best source of feedback you can get, but we need an MVP to get them in the system. From there we work on the features that you and your customers want most. I'll always give you straight talk on what options you have for various features, and steer you toward the most practical technology choices to handle the functionality you want, while also working within your budget. Core Services build a prototype or MVP jump into an existing application and work through a hard to build feature, or difficult bug improve the performance of your existing application improve your authentication layer (add popular authentication providers and protocols) improve your application security (evaluate and fix security holes, work through security questionnaires your clients send you) begin accepting payments in your application make your application mobile friendly (either using responsive / progressive design techniques or with a full fledged mobile app) give feedback on and improve your existing design Have an existing product? I specialize in performance enhancements to a product that feels a bit sluggish, as well as ensuring you can handle an expected jump in traffic pragmatic AI architecture. If you're not sure where to get started, I've already built out several multi-agent AI driven tool sets that go beyond having a context driven interaction with customers, and instead allow customers to handle complex tasks through text messaging and voice.

From the moment I wrote my first lines of code, I was drawn to the power of solving real-world problems through technology. Over the past 9+ years, I’ve honed my expertise in Ruby on Rails, Node.js, Python, Go, and React, building scalable, high-performance applications across FinTech, SaaS, and Healthcare industries. My passion lies in crafting robust backend systems, secure APIs, and seamless front-end experiences, all while optimizing for performance and maintainability. One of my proudest achievements was leading the migration of a monolithic Rails application to a microservices-based architecture using Go, Node.js, and GraphQL. By carefully refactoring services, implementing event-driven patterns with Kafka, and optimizing database queries, we cut response times by 60% and improved system reliability. This experience reinforced my belief that understanding the trade-offs of different technologies is key to building resilient applications. Beyond writing code, I thrive on mentoring engineers, leading technical discussions, and driving best practices in CI/CD, cloud-native development (AWS, Kubernetes, Terraform), and DevOps automation. I love tackling complex authentication challenges (OAuth, JWT, SAML) and designing secure, scalable APIs that empower businesses to move faster. At my core, I’m an engineer who bridges the gap between backend, frontend, and infrastructure—someone who doesn’t just build software but also optimizes it, secures it, and scales it. Whether it's refactoring legacy Rails applications, designing real-time systems with WebSockets, or deploying Go-based microservices, I bring a holistic, problem-solving mindset to every project.

Hello! I am a Rails and frontend developer who has worked at a variety of small companies and startups in various industries. This means I am a versatile problem solver who focuses on getting to the core of business problems before implementing solutions. In addition, I love working with people and am an engaged and helpful teammate. Recently, I have been working for a client on upgrading older Rails versions, implementing enhanced security mechanisms using devise and MFA, and of course building out features (e.g. billing). I have some strong AWS knowledge as well. I look forward to working with you!

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻
